One end of the medium tube is matched and connected with the medium outlet on the shell. The free end is provided with a medium through hole. The safe medium is the liquid which is antifreezing, heat resistant, anticorrosive or impact resistant and ensures the environmental adaptability of the pressure sensing element such as the pressure meter or the pressure switch connected with the safe medium. The utility model has simple structure, safety and long service life.
Description
The utility model relates to a kind of pressure sensor special pipe fitting, particularly a kind of fluid pressure-sensitive security medium pipe adapter.
At present, be used for the tensimeter and the pressure switch one class pressure sensor of abnormal temperature or environmental baseline, usually damage tensimeter or pressure switch because being subjected to the physicochemical property of fluid measured; Particularly under cold, high temperature, burn into vibration or shock environment condition, the usable range of this class tensimeter or pressure switch is limited to.
The purpose of this utility model is that a kind of fluid pressure-sensitive security medium pipe adapter will be provided, it can cooperate with tensimeter or pressure switch easily, with the action of its security medium controlled pressure table or pressure switch, improve the antifreeze, high temperature resistant, anticorrosion, anti-of tensimeter or pressure switch effectively and shake and impact resistance reliably.
The purpose of this utility model is achieved in that and is provided with security medium (4), fluid hose (3) and medium tube (6) in the inner chamber (12); Fluid hose (3) one ends are connected with fluid inlet (17), and its free end is provided with import aperture (5); Medium tube (6) one ends are connected with media outlet (8), and its free end is provided with medium through hole (7).Wherein, security medium (4) can be according to environment for use, selects to have antifreeze, high temperature resistant, anticorrosion, anti-shaking or the liquid of impact resistance respectively.Simultaneously, fluid inlet (17) end is provided with pipe fitting joint (15) and is connected external thread (13); Media outlet (8) end is provided with device joint (16) and is connected internal thread (9).
The utility model has been owing to adopted the version that is provided with security medium, fluid hose and medium in inner chamber, thus it reliably the controlled pressure table or pressure is opened and action, prevent that harmful fluid from entering this class pressure sensor; Simultaneously because fluid inlet end and media outlet end have pipe fitting joint and device joint respectively, so be easy to realize the cooperation that is connected with pressure sensor and pipeline; Because can selecting for use, security medium has antifreeze, high temperature resistant, anticorrosion, anti-shaking or the liquid of impact resistance in addition.So enlarged the range of application of this pipe adapter, improved adaptive capacity to environment; The utility model also has the advantage of simple in structure, safe and reliable and long service life.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the fluid pressure-sensitive security medium pipe joint structure synoptic diagram that the utility model proposes;
Fig. 2 is this pipe adapter and the manometric synoptic diagram that connects;
Fig. 3 is that this pipe adapter and switch connect synoptic diagram;
Wherein, Fig. 1 is the specification digest accompanying drawing.
Among the figure: 1, damping plug mouth, 2, damping plug, 3, fluid hose, 4, security medium, 5, the import aperture, 6, medium tube, 7, medium through hole, 8, media outlet, 9, connect internal thread, 10, tensimeter, 11, pressure switch, 12, inner chamber, 13, connect external thread, 14, the pressure sensor interface, 15, pipe fitting joint, 16, device joint, 17, fluid inlet, 18, housing.
When this pipe adapter and tensimeter connect, the security medium pipe adapter of at first selecting for use and be subjected to fluid measured to match.Tensimeter (10) is connected with the internal thread (9) that is connected of device joint (16), connect with the connection external thread (13) of pipe fitting joint (15) and the corresponding pipe fitting of hydraulic fluid pipeline to be measured.Then, hydraulic fluid to be measured enters damping plug (2) and fluid inlet (17) through damping plug mouth (1), flow into inner chamber (12) from import aperture (5) then, because the effect of hydrodynamic pressure, the fluid that enters inner chamber (12) promotes the security medium (4) in the inner chamber (12), makes it enter device joint (16) and tensimeter (10) through medium through hole (7), medium tube (6) and media outlet (8).Security medium (4) makes the fluid pressure value in tensimeter (10) the demonstration pipeline.Because security medium (4) condition that conforms, and be a kind of corresponding antifreeze, high temperature resistant, anticorrosion, anti-shaking or the liquid of impact resistance that have.Be subjected to the physics and the chemical stimulation of fluid measured can not directly act on tensimeter (10), enter tensimeter (10) but promote security medium (4), thereby guaranteed that tensimeter (10) can be in normal operating conditions with the pressure transfer mode.In addition because the structure of inner chamber (12) and import aperture (5), and the pressure effect of fluid circuit, the security medium (4) in the inner chamber (12) can be through import aperture (5) incoming fluid pipeline.Thereby guaranteed that the security medium (4) in the inner chamber (12) always is in the duty that makes tensimeter (10) pressure-sensitive.
When this pipe adapter and pressure switch connect, at first select the security medium pipe adapter that matches with pressure fluid for use.Pressure switch (11) is connected with the internal thread (9) that is connected of device joint (16).Connect with the connection external thread (13) of pipe connecting piece joint (15) and the corresponding pipe fitting of pressure fluid pipeline.Then, fluid in the pressure fluid pipeline enters damping plug (2) and fluid inlet (17) through damping plug mouth (1), flow into inner chamber (12) from import aperture (5) then, because the effect of hydrodynamic pressure, the fluid that enters inner chamber (12) promotes the security medium (4) in the inner chamber (12), makes it enter device joint (16) and pressure switch (11) through medium through hole (7), medium tube (6) and media outlet (8).Security medium (4) makes pressure switch (11) produce the pressure-sensitive action.Because security medium (4) condition that conforms, and be a kind of corresponding antifreeze, high temperature resistant, anticorrosion, anti-shaking or the liquid of impact resistance that have.The physics of pressure fluid and chemical stimulation can not directly act on pressure switch (11), enter pressure switch (11) but promote security medium (4) with the pressure transfer mode, thereby have guaranteed that pressure switch (11) can be in normal operating conditions.In addition because the structure of inner chamber (12) and import aperture (5), and the pressure effect of fluid circuit, the security medium (4) in the inner chamber (12) can be through import aperture (5) incoming fluid pipeline.Thereby guaranteed that the security medium (4) in the inner chamber (12) always is in the duty that makes pressure switch (11) pressure-sensitive.
